We started our build in October 2021 and we have successfully received a beautiful home for my mum to move into. Within these 7 months, every step of the way, each team member of five star builders held our hand and guided us through every step of the way. Tony helped us greatly in all aspects of admin and council dealings and spent time getting to us know as well. Sarkis and Anthony are super helpful, friendly and I found them professional yet personable at the same time. We were very impressed by the builders using “old school” techniques and actually building our granny flat using skill and brains, rather than precast ready made stuff. Mannan who overseas all the trades staff was here every morning at making sure deadlines were being met and work performed was to our satisfaction. I have no problem in recommending the team at Five Star Builders to anyone that needs a Granny Flat. Well done team. Another happy customer ticked off your list.
